Tools

• compare_vehicles ~201 tokens
  Compare the site's free projections for exactly two plates: identity, status and latest MOT test. Duplicate plates use one lookup. Includes questions from free facts, comparison image and report links. No prediction-based ranking; next-MOT estimates and likely repairs stay in the detailed re
• credits_balance ~89 tokens
  How many credits the user's RegTail account holds, and pricing_url, a page explaining how credits work. Needs the user's RegTail account linked.
• decode_plate ~152 tokens
  When a UK plate of this format could have been issued, from the plate alone (format, age identifier, and the window as first and last month). Offline: it does not look the car up; use free_check for that. No account needed.
• free_check ~227 tokens
  The site's free check: identity, tax and MOT status, latest MOT test, its defects and recorded mileage, the existing since-previous-test summary and mileage-unverified flag. Includes presentation, up to three questions from these free facts, a verdict image, locked teasers and a report link.
• full_report ~230 tokens
  The detailed report of a car the user has unlocked on their RegTail account: verdict and top risks, every MOT test with defects and advisories, mileage analysis, recurring advisories, other sections, the viewing checklist, what was not checked, and guidance for explaining it. Use to discuss
• my_reports ~94 tokens
  The cars the user has unlocked (with when each unlock ends) and their recent checks, so a conversation can pick up a car checked earlier. Needs the user's RegTail account linked.
• resolve_vehicle ~408 tokens
  Resolve a typed plate, car photo data URL or supported advert URL to a plate only. No account or spend. If uncertain, ask the user to confirm; if unavailable, ask for the typed plate. Then use free_check.
• sample_report ~128 tokens
  The detailed report and viewing advice for one public sample car (CX52HHM, a 2002 Land Rover Defender), to show what a detailed report contains. Use when the user asks what RegTail's detailed report looks like. No account needed. It is always the same sample car, never the user's car.
• unlock_report ~262 tokens
  Spends one of the user's RegTail credits to unlock the detailed report for this plate for 30 days, then returns the detailed report (as full_report does). Ask the user first, every time, and call this only after they agree; never unlock on your own initiative or to answer a general question.
• viewing_advice ~159 tokens
  Advice for viewing an unlocked car in person: a summary, priorities to check (each with why and the report records behind it) and known weak spots of the model. Needs the user's RegTail account linked and the plate unlocked; never spends.
